Protecting cpanel with htaccess

I seem to be getting a lot of "attempted" logins on my cpanel. To enhance the security further is it possible to use .htaccess to protect the cpanel login page; this obviously will make me login twice to get into cpanel but it will restrict the chances of someone succeeding a login by chance?

Does anyone know if it's possible and if so what directory shall I add the .htaccess to? It's on a dedicated server and I have full control of the server so I shouldn't have any restrictions adding this in.
